The purpose of this study was to comparison clinical applied versus theoretical fitness on axillary crutch in human stance phase. Ideal crutch length is defined as the length of the crutch, including accessories, obtained during stance when the crutch tip is 15 cm(about 6inch) lateral and 15 cm(about 6 inch) anterior to the fifth toe and the axillary pad is 5 cm(about 2 inch) below the axillay fold. The participations(volunteers) were 71 inpatients(53 men and 18 women) who have orthopedic and neurological impairment on unilateral and/or bilateral lower extrimities, and mean age was 31.4 year old. Prior to participation, each subject informed the procedures of experiment from researcher and assistant researcher. This measured for axillary crutch using each of the following aspects : (1) length of actual using crutch, (2) length of axillary fold after modified(77% of actual height), (3) angle of elbow flexion after modified(77% of actual height). In order to determine the statistical significance of result, t-test were applied at the 0.05 level of significance. The result were as follows ; 1. There was significant difference between actual crutch and ideal crutch length(77% of actual height)(p<0.05). 2. There was significant difference of length of axillary fold between actual and ideal crutch (77% of actual height)(p<0.05). 3. There was significant difference of angle of elbow flexion between actual and ideal crutch(77% of actual height)(p<0.05).

The purpose of this study was to determine which of several crutch-fitting techniques best predicts ideal crutch length. Ideal crutch length is defined as the length of the crutch, including accessories, obtained during stance when the crutch tip is 6 inches (15.2 cm) lateral and 6 inches(15.2 cm) anterior to the fifth toe and the axillary pad is 2.5 inches(6.4 cm) below the axillary fold. Forty four volunteers were measured for crutches using each of the following methods:(1) 77% of actual height, (2) actual height minus 40.6 cm, (3) actual height minus 45.7 cm, (4) olecranon to opposite third finger tip, (5) olecranon to opposite fifth finger tip, (6) 77% of arm span, (7) arm span minus 40.6 cm, (8) anterior axillary fold to heel plus 5.1 cm, (9) anterior axillary fold to heel plus 10.2 cm, (10) ideal crutch length. Of the techniques studied, the two involving anterior axillary fold to heel were found to be good predictors: anterior axillary fold to heel plus 5.1 cm and anterior axillary fold to heel plus 10.2 cm. Finally, two additional length estimates were derived using linear regression analyses. These estimates provided the best overall predictors based on anterior axillary fold to heel and actual height.
